The applicable information from all the entries present in ZoneDef.txt are imported into this index on server start. Any new non-grove zones (such as new dungeons) don't necessarily have to manually updated here.
Each line contains 4 values separated by the delimiter. They appear in this order:
Zone ID | Integer. Used as the table key. The Zone ID must be unique. |
Account ID | Integer. For groves, this is the Account ID of the owner. This property is used for enumerating groves via the /grove command. |
Warp Name | String. The full warp name of this zone, as when using the /warpi command. Case sensitive. |
Grove Name | String. For groves only. This should match the player account's grove name (see AccountList.txt) |
